Abstract [en]

Malaria is a major disease burden in the southeast part (Rangamati, Khagracharia andBandarban) of Bangladesh. This study uses satellite based data obtained from SPOT-5 forinvestigating association between land cover patterns and malaria incidences in an area of thatpart of Bangladesh. Climatic conditions were also examined to determine its influence onmosquito breeding and malaria incidences. Unsupervised classification was performed usingground-truth data to classify the land cover patterns of the area; and NDVI of the area wascomputed. Overall accuracies of 89.9%, 87.9% and 89.5% were achieved in Kuhalong,Shuloka and Bandarban respectively. These data sets were used to predict risk for malariautilizing statistical tools of the SPSS software. Factor analysis was carried out to investigaterelationship between land cover patterns and malaria cases in the different subunits (calledunions) of the study area. Malaria cases were not evenly distributed among the unions. InKuhalong union, there were more malaria cases compared to the other unions, Shuloka andBandarban. Kuhalong is covered with more water bodies than that in the other two unions.The results of the analysis illustrate malaria cases are correlated with land cover like water,light forest, and agricultural land; and are also associated with average humidity and averageNDVI.
